Application filed October 23, 1920. Serial No. 418,887.

I washing dishes, and more particularly one in which the dishes areplacedin a closed stationary receptacle and subjected to the cleansingaction of a plurality of streams of water sprayed over the same. l

The invention has for its object to provide a very simple and eiiicientapparatps of the kind stated, and one in which the spraying action isobtained by a very simple expedient.

With the object stated in view, the invention consists in a novelcombination and arrangement of parts to be hereinafter described andclaimed, and in order that the. same may be better understood, referenceis had to the accompanying drawing forming a part of the specificationIn the drawing,

' Figure l is a central longitudinal section of the apparatus, and Fig.2 is a cross-section thereof.

Referring specifically to the drawing, 5 denotes a water-tightreceptacle of any suitable contour and dimension, in whichv the dishesto be washed are placed, access to the receptacle being had by havingthe same open at the top. A tight fitting hinged door 6 is rovided forthe top of the receptacle, and in the receptacle are mounted'suitableracks 7 which support the dishes shown at 8.

Passing centrally through the receptacle 5 is a rotatable spray pipe 9which is provided with a large number of perforations 10 throughwhichlthe water is dlseharged. One

end of the pipe 9 is closed and this end is sup ported in a bearin 11mounted on the cone spohding end wal of the receptacle The other end ofthe pipe 5 is open and is supported in a bearing 12 mounted on thecorresponding end wall of the receptacle. The

bearing .12 has a nipple 13 which passes through the end wall of thereceptacle, and on the outside of pled to obtainlng hot water from anysuitable source. The bore of the nipple 13 is in communication with theopen end of the pipe 9, and hence, when the water is turned on, it flowsnto said plpe and is sprayed through perrorations 10 thereof over thedishes 8.

One end of the pipe 9 is fitted with two diametrically opposite, andradiallyextendng discharge tubes 15 from which the water 1s dischargedat their outer ends, said ends being bent laterally toobtain atangential d1scharge. The reaction of the water discharged from thetubes 15 at the outer ends thereof causes said arms to revolve and thusrotate pipe 9, with the result that the water dlscharging from theperforations 10 1s contmuallyeprayed over the dishes 8, and the latterare rapidly and thoroughly cleansed. The receptacle is provided with adrain 16.

The apparatus is very simple and efficient, and 1t is well adapted fordomestic use as itcan be operated by connecting the hose 14 to the hotwater faucet in the kitchen. Theapparatus 1s alsoeconomicalin operationas the amount than that ordinarily used when washing and rinsing dishesby hand. I

lclaimz A Washing apparatus comprising a receptacle, a perforated spraypipe extending horizontally and centrally between the opposite end wallsof the receptacle and rotatably supported, a water supply connection tothe pipe, radlally extending discharge tubes carried by the spray pipeadjacent to one end thereof for rotating said pipe by the reaction ofthe water discharged from the outer ends of said tubes, and dishsupporting racks mounted in the receptacle parallel to the spray pipe,and located above and below the same.

In testimony whereof I afllx my signature.
